Re: ferric oxalic



I just mixed up a fresh supply this week. I heated distilled water to ~130F added it to the FO powder, capped and shook the bottle. I then stood the bottle in a water bath at about the same temperature. I was doing other things in my darkroom and would occasionally shake the bottle some more. When I left the darkroom I left the bottle standing in the water bath. The next day the FO was completely dissolved.

Hello to all. Treatment of dissolving ferric oxalato, but he/she is not dissolved. I already know that the oxalato has problem to dissolve. Some method? Once dissolved, should he/she filter the solution? Thank you, excuse for my English, text translated by computer.
